Read errors aren't pushed into the stream

[Silic0nS0ldier]

An issue with error reporting has been identified and needs to be resolved.

1. The read function is unnecessary marked as async
2. The exception should be pushed into the stream, but isn't.

vinyl-fs-vpath/src/src.ts

Lines 86 to 114 in f37d98f

	/**
	* Internal only. Instructs that a new file needs to be pushed out.

	async _read() {
	while (this.files.length > 0) {
	const { actual, virtual } = this.files.pop();
	try {
	const file = vinylFile.readSync(actual, this.vinylFsSrcOptions);
	if (actual !== virtual) {
	file.path = virtual;
	}
	this.logger.trace("Pushing file", { actual, virtual });
	this.push(file);
	return;
	/* c8 ignore next 4 */
	} catch (error) {
	// This can happen when there are file changes during processing, difficult to test
	throw new PluginError("userfrosting/vinyl-fs-vpath", error);
	}
